Urologists are physicians who specialize in the diagnosis and treatment of conditions related to the urinary tract and the male reproductive system. Other health professionals who treat urinary or urogenital problems include primary care physicians, pediatricians, gynecologists, urogynecologists, and nephrologists.

Anus. Theopening at the end of the digestive tract where bowel contents leave the body.

Bladder.A triangle-shaped, hollow organ located in the lower abdomen that holds urine. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.

Penis. The outer reproductive organ of a male.

Rectum. Thelower end of the large intestine, leading to the anus.

Scrotum. The bag of skin that holds the testicles.

Testis.One of the pair of male gonads that produce semen; suspended in the scrotum by the spermatic cords.

Tunica vaginalis. A thin pouch that holds the testes within the scrotum.

Urethra. Anarrow channel through which urine passes from the bladder out of the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra. When all the signals occur in the correct order, normal urination occurs.

Overview of the urinary tract

The urinary tract or system includes the organ system primarily responsible for cleaning and filtering excess fluid and waste material from the blood:

Kidneys

Ureters

Bladder

Urethra

The kidneys also function as glands that produce hormones necessary for building red blood cells and regulating blood pressure.

What is the male urogenital system?

The male urogenital tract includes the following:

Testes

Efferent ducts

Epididymis

Ejaculatory ducts

Ductus deferens

Urethra

Penis

Accessory glands:

Prostate

Seminal vesicles

Bulbourethral

What causes problems in the urinary system?

Problems in the urinary system may include conditions such as kidney failure, urinary tract infections, kidney stones, prostate enlargement, and bladder control problems. These problems in the urinary system may be caused by the following:

Aging. As we age, changes in the structure of the kidneys can cause them to lose some ability to remove wastes from the blood, and the muscles in the ureters, bladder, and urethra tend to lose some of their strength.

Urinary infections may occur because the bladder muscles do not tighten enough to empty the bladder completely. A decrease in strength of the muscles of the sphincters and pelvis, that may be associated with age, can also cause incontinence.

Illness or injury. Damage to the kidneys caused by illness or an injury can also prevent them from filtering the blood completely or block the passage of urine.

Are urogenital diseases common in the United States?

Diseases of the kidney and urinary tract remain a major cause of illness and death in the United States. The National Kidney Foundation (NKF) states that more than 26 million Americans are affected by kidney and urologic diseases, and millions more are at risk.

What are the symptoms of a kidney and/or urinary tract disease?

The following are the most common symptoms of a kidney and/or urinary tract disease. However, each individual may experience symptoms differently. Symptoms may include:
